I am running the Chirpstack v3.3.3 on a raspberry pi 4. When installing and configuring I always have a monitor connected to the RPi and it Chirpstack works fine.
-
When removing the HDMI cable from the Rpi and restarting it does not boot at all
-
Solution: configure the config.txt on the SD card when accessing the SD card from another PC (not via the RPi)
/## hdmi_force_hotplug
/## Pretends HDMI hotplug signal is asserted so it appears a HDMI display
/## is attached
/##
/## Value Description
/## -------------------------------------------------------------------------
/## 0 Disabled (Default)
/## 1 Use HDMI mode even if no HDMI monitor is detected
/##
hdmi_force_hotplug=1 -
Booting the RPi now works without monitor
However it seems that after a time (15 minutes or so) the chirpstack does not react (MQTT no longer received). With monitor it all worked very smooth.
Any idea what the cause could be?? (sleep timer??)
